Hi,

I have created a lamp post which is supposed to light up at night. It is made up of a cylinder(the base) and a sphere.

How do I create the effect of the lamp post lighting up at night?
I placed a light source at the position of the sphere and adjusted the diffuse values. But the entire scene is lighted up instead.

I also tried using emissive materials for the sphere but it did not have the "lighting up" effect.
